![A solid aluminum alloy [E = 69 GPa; a = 23.6 × 106/C] rod (1) is attached rigidly to a solid brass [E = 115 GPa;
a = 18.7 × 10-6/°C] rod (2), as shown in the figure. The compound rod is subjected to a tensile load of P = 6.4 kN. The diameter of
each rod is 12 mm. The rods lengths are L₁ = 523 mm and L₂ = 675 mm. Compute the change in temperature required to produce
zero horizontal deflection at end C of the compound rod.
